RESETLOGS option.
D. Restore the latest backup control file, perform incomplete recovery using backup control file, and open

Answer: D

争议点：
网上有人说选择B，
比如：
LuiseDalian的解析：http://blog.itpub.net/17013648/viewspace-1326753/

如果是控制文件和active online redo文件损坏，那么oracle只能做不完全恢复，
做不完全恢复就必须把最近备份的整个数据库转储出来，然后做recovery，恢复的失败的那一点。

也有遵循题库的答案解析，选择D：
比如：
Riveore的解析：http://blog.csdn.net/rlhua/article/details/14649045

戴总整理的题库此题也是D选项。

争议点在于，做不完全恢复，是否一定需要把最近的整个数据库转储出来；

初步结论：
保留争议，暂时选择B。
